My brother is a commercial pilot and I think many people would be terrified of how many issues routinely arise on a normal flight if they were told about them.

My brother is a commercial pilot and I think many people would be terrified of how many issues routinely arise on a normal flight if they were told about them. When everything double/triple redundancy and procedures are so regimented it rarely warrants mention and causes undue worry. In contrast a flight with no engineering issues through heavy weather and turbulence would have many in the cabin stressed.
